But on this car, 6-pots are probably overkill in stock trim. I have a 2004 Saturn VUE with the Honda 3.5 24V V6 with a 5-speed auto, and that vehicle is MUCH more responsive to drive than my SVX. I think the Honda 3.5 is rated at 250hp, so it has more hp than the SVX, but the VUE just gets up and goes without too much effort. On the SVX, it has a much more leisurely acceleration pace, unless you mash the gas pedal. That's fine by me, it's not really a sports car, more of a sports tourer, and for that it does a great job!

Try driving a manual transmission SVX; completely different animal. With the 4EAT engine revs are soaked up by the torque converter first, but with the 6-speed the SVX is more jumpy than my Legacy in Sport Sharp drive mode.

Yeah, given a choice in this car, I'd much rather have a manual than the automatic. But since they didn't come with manuals in the States, it is what it is. I'm okay with that, I have the VUE, two Triumph motorcycles, numerous firearms, one daughter doing grad school in Ireland, and another one ready to graduate from the University of Hawaii, so it's not like I don't have other things to spend my limited funds on, lol...

I agree 4/2 is good and will do great on the svx, 6 is just for looks/overkill, I would do it if money would let me, but not required.

And ya with a manual, especially 6 speed this svx wakes up you will never look at the car the same. If I can make it to the 25th meet I would let people drive to see for themselves.
I have the engine, I just need to drop it in, I should swap over my waterpump/timing belt as mine are new and I don't know anything about these but water pump gasket isn't in my current budget lmao.

Ryan Clark, not sure if he is on the forum here, is working on an adapter that will bolt up with cheap 4 pots that can be found here.

I don't know if your famaliar with some of the wrx community happenings, but caddilac has a very cheap brembo that bolts up to wrx's with a simple adapter that is now easy to get, I believe with a adapter those cheap brembos should work with the svx

Yea, I am here. The caddy brembos require a bracket and a 355mm rotor. Project is on hold while I get my svx ready for car season.

From my research it seems the calipers are functionally the same, it's the mounting point that was modified in 2008 - it went from a backing plate design to an ear-on-knuckle design. This moved the caliper offset by approximately 4mm which is why you want 2006-2007 rotors. To swap backing plates, you need to remove the rear wheel bearings. This would be a good time to replace wheel bearings.

As for the FRONT brakes, it appears that Subaru made a custom knuckle with caliper mounting tabs that are located slightly further away from the hub than any other Subaru ever made. What this means is that any other subaru caliper you want to use will be ever so slightly too far away to fit precisely over the oem size 2006-2017 rotors. I am not sure how much the difference is, but I have read anywhere from 1 cm to 15mm. Not verified by me. What this means is that you could modify the metal tabs on the knuckle to move the bolt holes closer to the hub. I do not know how feasible this would be with clearance of other knuckle components, however, I think this *might* work. Alternatively, you can source a custom made bracket that adapts to the more current "Brembo GT calipers" made in 4 and 6 piston styles. These brackets allow these calipers to work with 355xx x 32mm rotors (Mustang GT500 size). The downside here is that you'll likely pay a bit more money for the Brembo GT style caliper, and you'll need to locate a pair of said brackets. If you're a stickler for looks like I am, you'll also need to custom paint/powdercoat all 4 calipers to match.

The following is a cut and paste from the SVX Nation Face Book thread on the upgrade of the front calipers to 4 pot.

"So after seeing a bit of interest in doing the 06/07 wrx and jdm 4/2 pot caliper swaps, we have decided to put a feeler up for anyone interested in our customs cnc'd front caliper spacers. These are designed to widen the front 4 pot calipers to accommodate a Tribeca front rotor on our SVX's. Shout out to Ryan Clark for doing all of the mock up work so we had the measurements correct to make these.
Prices will be as follows, and will be based on the number of people interested.
1-9@$90/set
10-19@$80/set
20+@$70/set
One set includes 4 total spacers for 2 front 4 pot calipers.
I will leave this post up for one week with a running list of interested parties. At the end of the week, I will take payments for interested parties and submit the order. I'm being told it should be about a 2 week turn around from the time the order is submitted to the time of completion due to a heavy volume of work at the machine shop.

*note* you will need further components to complete this swap not included with these spacers
-Tribeca front rotors [any year]
[06/07 wrx calipers]
-z32 caliper pinshttps://www.z1motorsports.com/…/fron...mm-and-…
-an extra set of caliper o-rings, same part number as whats in the caliper rebuild kits. Here is a link to a kit for just the extra set of o-ringshttps://www.z1motorsports.com/…/z32-...ng-kit-…
I will keep a running list on this post, so please pm me of you have any questions or interest in getting on the list so its easier for me to keep track. "

In our mind not too bad a tested and verified option. The only known issue is wheel clearance with the oem wheels. May need a pair of 5mm wheel spacers to clear the oem wheels at 10-20$. Oh, info in [ ] are my adds to clarify the info. Not our investigation, not our info or parts order.

Very short time to get in on this as the spacer order will be submitted Feb. 2 2018!!!

Could we not just switch hubs with a Tribeca or MY05+ STI so that Brake parts are more universal?

I know that the splines are different on the half shafts(an hub), but wouldn't taking the hub side of the half shaft apart and switch to the half shaft with the appropriate shaft spline for the hub.

Its a little more work at the beginning but may be cheaper and pay off in the end.

This would not be possible without fabrication work. It has been looked at and abandoned by at least one member. The lower balljoint is completely different on the GD chassis cars so the knuckle will not just bolt on. The CV shaft splines are actually the same, so that is not the issue. But getting the knuckle bolted on is the problem.

So HarversterUT, Have you done this swap? Does this swap use the 2 pot calipers and what is the thickness of the rotors? I'm considering during the upgrade for the front rotors/calipers being offered by SVXNation which uses Tribeca rotors and WRX 4 pots. Wondering what the combined effect would be?
